The road was effectively London's first
bypass. Construction of the
New Road, as it was called, began in 1756 along the northern edge of the built-up area. In 1857, the road's name was changed from New Road, with sections, west to east, renamed Marylebone Road, Euston Road and Pentonville Road. The name
Marylebone originates from a church, called "St Mary Le Bon", that was built on the bank of a small
stream or "bourne" called the tybourne, in an area named after the stream
Tyburn. The church and the surrounding area later became known as St Mary at the bourne, which over time became shortened to its present form
Marylebone. The current
St Marylebone Parish Church is on the south of Marylebone Road, opposite the
Royal Academy of Music and at the top of
Marylebone High Street. The crossroads of Marylebone Road and
Baker Street was historically known as
Marylebone Circus, which is still its unofficial name. ==Tourism==
